Unformatted text preview: 5) An X-ray photon scatters from a free electron at rest at an angle of 175 relative to the incident direction. If the scattered photon has a wavelength of 0.32 nm, what is the wavelength of the incident photon? 6) What speed must a neutron have if its de Broglie wavelength is to be equal to the interionic spacing of table salt (0.282 nm)? 7) The uncertainty in position of a proton confined to the nucleus of an atom is roughly the diameter of the nucleus. If this diameter is 7.5x10-15 m, what is the uncertainty in the protons momentum? 8) The measurement of an electrons energy requires a time of 10 ns. What is the smallest possible uncertainty in the electrons energy?...
